Q:

We want to assign port 3 of our Catalyst 2950 switch to VLAN 3. What command will achieve this?

A) switch(config-if)#switchport vlan 3 B) switch#switchport access vlan 3
C) switch(config)#switchport access vlan 3 D) switch(config-if)#switchport access vlan 3
 
Answer & Explanation Answer: D) switch(config-if)#switchport access vlan 3

Explanation:

Explanation: The switchport access vlan [number] command will configure a switch port to that VLAN. You can also use the switchport access vlan dynamic command to configure the switch port automatically in a certain VLAN depending on the VLAN membership of the incoming packets. For both commands to work properly the switch port needs to be in access mode

C. 66.55.128.1
D. 135.1.64.34

Q:

If one of the host connected to Sw-AC3 wants to send message to ip 190.0.2.5 (or any ip on a different subnet) what will be the destination MAC address ?

Answer

Answer and Explanation:


Because the destination address is on a different subnet from the switch, the packet will be forwarded to its default gateway. To verify the default gateway of this switch, use the show running-config command



From the output above, we can see that its default-gateway is 192.168.1.254. Which can be said to be a layer 3 device (router); in this case, the VLAN-R1 router. You can use the show cdp neighbor detail command verify further.



From the output above, you can confirm that the switch's default gateway is VLAN-R1 router (with the IP address of 192.168.1.254).The interface FastEthernet0/3 shows that the switch is directly connected to VLAN-R1 router through the switchport Fa0/3. To verify the MAC address associated this interface is interface, you use the show mac-address-table command:



Looking closely at the table above, you will discorver that the corresponding MAC address is 000a.b7e9.8360. Although there are some entries on port Fa0/3 with different Vlans ,but they have the same MAC address.
